For a given unbalanced reaction, \(\mathrm{MnO}_2+\mathrm{HCl} \longrightarrow \mathrm{MnCl}_2+\mathrm{H}_2 \mathrm{O}\), which is the limiting reagent, if the initial amount for each of the reactant is 100 grams? [Molar masses : \(\mathrm{MnO}_2=86.9 ; \mathrm{HCl}=36.5\); \(\left.\mathrm{MnCl}_2=125.8 ; \mathrm{Cl}_2=70.9 ; \mathrm{H}_2 \mathrm{O}=18\right]\)
- A \(\mathrm{MnO}_2\)
- B \(\mathrm{HCl}\)
- C \(\mathrm{MnCl}_2\)
- D \(\mathrm{Cl}_2\)
Answer & Solution
Correct Answer
(B) \(\mathrm{HCl}\)
Step-by-step Solution
Detailed explanation
Limiting reagent In a chemical reaction, the limiting reagent is the reactant that determine, how much of the products are made. The other reactants are sometimes referred to as being in excess, since there will be some leftover after the limiting reagent is completely used up.…
